Comprehensive evaluation of polar weather research and forecasting model performance in the Antarctic

Abstract: [1] Recent versions of the Polar Weather Research and Forecasting model are evaluated over the Antarctic to assess the impact of model improvements, resolution, large-scale circulation variability, and uncertainty in initial and lateral boundary conditions. The model skill differs more between forecasts using different sources of lateral boundary data than between forecasts from different model versions or simulated years. Using the ERA-Interim reanalysis for initial and lateral boundary conditions produces th… Show more

“…Much attention has focused on Antarctica's energy budget in recent years, notably due to the West Antarctic Ice Sheet warming (O'Donnell et al, 2011;Bromwich et al, 2013b), and on large ice mass loss (gain) recorded in West (East) Antarctica (Harig and Simons, 2015). In order to assess how atmospherically driven processes affect the evolution of Antarctica's ice mass and surface energy budget, our understanding and modelling of the clouds in that region must be improved.…”

“…In this context, it is of vital importance to monitor and understand the processes controlling the surface heat and mass exchanges between the Antarctic Ice Sheet and the atmosphere. As in other regions of the world, meteorological reanalyses are commonly used, either as climate series to interpret or even detect recent changes (Bromwich et al, 2012) or as boundary conditions for regional meteorological and climate models (Van de Berg et al, 2008;Gallée and Gorodetskaya, 2010;Bromwich et al, 2013). However, the scarcity of assimilated observations constraining the analysis, along with weaknesses in the modeling of some key processes for the polar regions -such as the formation of mixed-phase clouds and the extreme stability of the atmospheric boundary layer (ABL) -increase the uncertainty in the quality of the reanalyses over Antarctica.…”

The AMPS archive is the repository of gridded output from AMPS from over the years (Powers et al, 2012), and WRF gridded output from the archive has supported numerous studies Cassano, 2008, 2012;Schlosser et al, 2010aSchlosser et al, , 2016.…”
